五氧化二磷制备

1.氧化法将黄磷加热熔融后，送入氧化燃烧炉，用干燥空气(经浓硫酸脱水)进行氧化燃烧反应，生成五氧化二磷因受热而升华，在炉顶遇冷而落入氧化燃烧炉底部的沉降室内，制得五氧化二磷成品。由氧化燃烧炉逸出的尾气经旋风分离器以回收五氧化二磷粉尘。回收成品与沉降室中的产品一起作为成品包装。其4P+5O2→2P2O5以试剂级五氧化二磷为原料，在充分干燥的氧气气流中灼烧升华提纯，经冷凝器捕集升华物，制得高纯五氧化二磷成品。

2.在广口瓶上安装一个用马口铁制成的宽口漏斗，漏斗上倒罩着一个比漏斗口小的衬锡的马口铁圆筒(直径350mm，高500mm)。圆筒底部装入通气弯管，中上部开有一口，是用来安装燃烧勺用的。加热燃烧勺，向勺中放入干燥的白磷，迅速插入圆筒中，并借燃烧勺柄上的塞子固定在圆筒上。当磷烧尽后再重复此操作。通气强度和燃烧速度可由调节圆筒与漏斗间的缝隙大小控制。燃烧生成的氧化磷在圆筒内壁上冷却。轻轻敲动圆筒就落入广口瓶中。提纯市场上或上述所制得的氧化磷常含有磷的低价氧化物，有时还含有黄磷，一般实验可直接使用，欲需要较纯的可进一步在干燥的氧气流中灼烧升华制取。将一干燥清洁的T型管倒置，管口上安装放有起始原料的P2O5玻管。从T型管的一端通入经CaCl2干燥的氧气，另一端接玻璃冷却管。将待灼烧升华的P2O5放入T型管中加热。200g市售样品在2h后可得到大约70g纯品。以试剂级五氧化二磷为原料，在充分干燥的氧气气流中灼烧升华提纯，经冷凝器捕集升华物，制得高纯五氧化二磷成品。

3.在预先经浓硫酸、固体氢氧化钾和工业品五氧化二磷干燥过的纯氧气流作用下，将工业品五氧化二磷升华提纯，可得不含低级氧化物的五氧化二磷。
